I did this a bunch during the cheap award flights during the pandemic, when they started counting those toward status points.

I basically skipped getting a coworking spot for a month and would hop on random flights I could book like SAN-JFK round trip same day on delta for only 16,000 skymiles (would net around 5,000 mqms). I would almost always get bumped to first and Deltas wifi is reliable enough to work from the air.

At this point I’ve banked enough MQMs that I just have to hit the spend min on my Amex (easy when you are self employed and can pay taxes on it) to keep platinum for the next 3 years without any flying.
